Polymorphism of alpha-amylase and conjugation in common wheat enzyme types with quantitative traits of plants

Using the polymorphism of α-amylase in the culture of winter common wheat, the inheritance of isoenzymes of this enzyme and conjugation of its enzyme types with germinating grain on the “vine,” grain productivity, plant height, and time of ear formation have been studied. It has been shown that the polymorphism of α-amylase isoenzymes in common wheat is limited by the presence of different loci, whose products are similar in electrophoretic parameters. In this regard, one component of the enzyme can be controlled by one, two, or three genes. The locus, which controls α-amylase isoenzyme in the fast moving part of the electrophoretogram, designated as α-Amy-B7 has been identified. The distance of the locus to factor α-Amy-B6 has been determined.
